Formation
Trainer on one side with two blockers in front in zone 2-3 or 3-4.
On the opposite side: Libero in reception, setter around 2/3, and two attackers (e.g., outside hitter + middle blocker, or outside hitter + opposite hitter).

Green: Set up to position 4 for a line attack.

Red: Set up to the middle for a tip over the block.
Yellow: Set up to the corner (inside) or middle for a deep hit to position 5.
